Deeper version of M13

Decided to try 240s exposures in each of RGB this time instead of my usual 180s (chosen to balance detail and LP) and it seems to have worked well, especially since there only 5 subs of each colour. Much deeper into the fainter stars too.

First proper imaging session of the season. New mount (EQ6-R) is guiding well with an RMS error of about 0.6″, Coma corrector is working well too. Stars are sharp right to the edges.
